High Performance Thin Layer Chromatography: A Qualitative Biochemical Analysis of Sammoha Loha Vati Formulations

Qualitative Metabolism Assessment Using High Performance Thin Layer Chromatography

Application of High Performance Thin Layer Chromatography for Qualitative Analysis of Isoflavones in Medicinal Plants

The retention behavior of commonly occurring compounds with estrogenic activity: daidzein, formononetin, genistein, prunetin, biochanin A and coumestrol on silica and silica modified with cyjanopropyl, aminopropyl, diol and octadecyl groups was investigated. Mixtures of methanol or acetonitrile with water and eluents such as chloroform, heptane and toluene with more polar modifiers: ethyl aceta...

Qualitative high performance thin layer chromatography (HPTLC) analysis of cannabinoids in urine samples of Cannabis abusers.

BACKGROUND & OBJECTIVES Cannabis is one of the most commonly abused drugs worldwide. There is a distinct clinical correlation between cannabis abuse and mental disorders. However, it is essential to establish cannabis intake in the abusers in order to establish causality between cannabis and psychiatric illness. The limitations of current detection methods using commercial cassettes prompted us...

Determination of active ingredient in synthetic pyrethroid formulations by high-performance thin-layer chromatography/densitometry.

A new, simple, precise, and rapid high-performance thin-layer chromatography (HPTLC) method was developed for the analysis of commercial emulsifiable concentrate (EC) formulations of cypermethrin, alpha-cypermethrin, and lambda-cyhalothrin. A known amount of reference grade synthetic pyrethroid and its EC formulation was subjected to TLC, and the amount of pesticide present in the active ingred...

Quantitative Estimation of Efavirenz by High Performance Thin Layer Chromatography

A simple, accurate, and precise HPTLC method has been developed and validated for the estimation of efavirenz from bulk drug and capsule formulations. The separation was achieved on TLC plates using an appropriate solvent system. The spots so developed were densometrically scanned at 247 nm. The linearity of the method was found to be within the concentration range of 1-40 μg/ml. The validation...
